Soluble graphite ink composition

Abstract

An erasable soluble graphite ink composition that may be adapted to an existing dauber applicator, resembling a writing instrument such as a pen or pencil. When applied by the dauber to a writing surface, provides for a machine-readable pattern. The dauber, when filled and utilized with the present composition and its alternate embodiments, allows for the rapid filling of apertures in one motion of the dauber, versus repetitive circling when using a conventional pencil. Such filling is viewed as saving between three to five times (3×-5×) the amount of time and is considered advantageous during usage in situations where time saving is a critical factor. Once applied to the writing surface, the composition may be erased using a standard pencil eraser, and remarked such that only the revised mark is read by the machine reader.
